ROLL-SIDE KEY-OPENING can.

Specification of Letters-Patent.

Patented Sept. 6, 1910.

Application filed February 10, 1910. Serial No. 543,064.

To all whom it may concern:

Be it known that I, WILLIAM E. TAYLOR, a citizen of the United States, residing in Eastport, in the county of Washington and State of Maine, have invented a new and useful Improvement in Roll-Side Key-Opening Cans, of which the following is a specification.

Myinvention relates to key opening cans.

The object of my invention is to provide a key opening can of a simple and eflicient construction, in which the can will open easily and conveniently and with certainty and reliability or without dan er of failure, in which the cans will openromthe side and in such manner that the fish or other contents of the can may he slipped out in a solid block or cake without mutilation or mussing, in which the liquid contents of the can may be retained therein without spilling after the can has been opened, when desired, which will be of such construction that both heads of the can, or both top and bot tom' may be secured to the body'by double seams without solder, and which will open with e ual facility, however the key may .e, and thus render it impossible to apply t ie key wrong end to, and thereby cause failure to open as often happens with rolltop key opening cans and other cans now in use, and in which also in openingthe cans, the lines of separation or tearing will always truly anda-ccuratcly follow the scores or weakened lines andnot tend to depart therefrom as frequently happens in key opening cans now in use.

My invention consists in the means I employ to practically accomplish in a single unitary structure or can, these objects or results as herein shown and described and more particularly. specified in the claims.

In the accompanying drawing forming a part of this specification, Figure 1 is an end elevation of a roll side key opening can embodyingmyinvention. Fig. 2 is a horizontal section on llne 22 of Fig. 1. Fig. 3 1s a cross section on,line 3-3 of Fig. 2.

r Fig. 4 is a detail front elevation showing the can after being opened Fig. 5 is an enlarged detail vertical section on line 5-5 of Fig. 2. Fig. 6 is an end elevation illustrating a modification in which the projecting tongue or lip is omitted, and a puncture tongue or lip employed in place of a projecting one.

In the drawing 1 have illustrated my inventlon as applied to a rectangular sardine can with rounded corners, it being specially adapted for sardine can use.

In said drawing, 1 represents the body of acan, the same having a soldered lap side seam 2, and a lip or tongue 3 externally projectin'g beyond the lap seam, for the reception of the key 4 to start the winding. The top and bottom heads 5 of the can each have a countersunk wall 6 fitting snugly within the end of the can bod and a. seaming flange 7 which is interfo ded into a double seam 8 with the seaming flange 9 of the body. The roll side 10 of the can extends along one of the longitudinal sides of the can and partially along the adjacent ends or around the curved corners 11 'of the can, so that when the roll side 10 is rolled about the key I 4 in opening the can, the fish or other solid contents of the can may be then slipped out in a solid block or cake, and so that also the liquid contents maybe retained in the can after it is Opened as long as may be desired, by' simply placing it with its open side uppermost. The roll side of the can is bounded at its -up or and lower edges by scores or weakene lines 12, which are located closely adjacent to the pit or'inner edge 13- of the double seam 8 which unites each of the heads 5 to the can body, so that the pits or inner edges of the double seams mutilated cake or block through the open side after the can has been opened by winding the roll side about thekey, the scores or weakened lines .12 are located outside of or beyond the inner ed es 14 of the countersunk wall 6 so that t e opening in the side of the can will be of reater width than the distance between the lnner faces of the top and bottom heads 5, 5 of the can. In other words, each of the scores or weakened lines is between the shoulder or inner edge 14 formed by the countersunk wall 6 and the i pit or inner edge 13 of the double seam 8.

' tersunk wall 6 of the can heads and of the external double seams 8 and of the scores or weakened lines 12 not only causes the opening produced by the roll side to be of greater extent in the side of the can body than the space between the can heads 5, 5, and thus to enable the contents to be removed in a solid block, but it also serves a very important function in opening the can, as the internal Walls or shoulders 6 afiord a very strong and rigid support directly opposite the lines of tear in opening the can by winding the roll side about the key. The scores or weakened lines 12 between the double seams 8 and the inner faces bf the can heads preferably have converging portions 16 at the projecting lip or tongue portion 3 of the can body near the side seam 2 thereof to give the lip .or tongue 3 a narrower or somewhat pointed end, as will be readily understood from Fig. 1 of the drawing.

In the modification illustrated in Fig. 6, the lap side seam 2 is located near the middle of one end of the can body, and the externally projecting lip or tongue 3 to receive the slotof the key is omitted; and the can body instead is provided with a puncture lip or tongue 17 adapted to be cut-or ruptured at the apex 18 formed by the crossing scores or weakened lines 19 with a sharp pointed or sharp edged key. With this exception, the construction shown in Fig. 6 is the same as that illustrated in Figs. 1 to 5.. The overlapping members of the lap seam 2 of the can body are preferably furnished with the customary indentations or holding devices 20.

The roll side 10 of the can body preferably is in or extends across one ofthe longer sides of. the rectangular can body instead of in or across one 0 its shorter sides, although a clear openin of the full cross sectional interior size 0 the can is obviously produced by my inventiomwhichever of thefoiir sides of the can body he removed by winding the roll'side about the key.

In practicing my invention, whatever the shape or form of the can body to which it is applied, the scores or weakened lines of the roll side should be made long or extensive enough to produce a clear opening in the can body--one of the full size of the contents of the can-so that the contents may, if solid, be removed or slipped out of the can in a solid, unmutilated cake or block.

ing a can body, can heads having countersunk walls fitting inside the can body, external double seams uniting the can heads to the can body, said can body havinga roll side, and at each edge of said roll side a weakened line between the adjacent inner face of one of said can heads and the double seam uniting such head to the can body, said countersunk walls and said double seams supporting the metal of the can body on oppositntsidesadjacent to said weakened lines, substantially. as specified ing countersunk walls, of a canbody provided with a roll side wider than the space lgotweenthecan heads, said can body having scores at the edges of said roll side, said can body andcan heads having external double seams closely adjacent to said scores, said countersunk walls and said double seams supporting the metal of the can body on opposite sides adjacent to said weakened lines,

externally projecting lip at one extremity thereof adjacent to the side seam of the can body, substantially as specified.
